I don't have any isolation transformer or Variac. (Actually, I have an isolation transformer but I don't use it) I guess I live on the wild side. My hair is curly because I have been electrocuted more times than Kirk (Old Restorer). What I DO do is to correct the "Switch in the Neutral" syndrome that hot and warm chassis sets suffer from.
An isolation transformer should not trip a GFCI if all the filters are on the secondary of the transformer. (I believe that the GFCI does not measure the amount of current on the ground, it measures the difference between "Line" current and "Neutral" current. In fact, on some of our installations with multiple computers in the same power line, we were required to install an isolation transformer to comply with IEC60601 leakage specs due to the multiple Hopkins filters in the same line.
